The present invention relates to a refrigerator, and more particularly, to a cold air flow passage structure for allowing ice, which is received in an ice-storing device provided in a refrigerating chamber door, to be in a frozen state without being melted. The refrigerator of the present invention comprises a main body including at least a refrigerating chamber and a cold air flow passage for supplying cold air to the refrigerating chamber, a refrigerating chamber door for opening or closing the refrigerating chamber, a shelf provided in the refrigerating chamber, and a container provided in the refrigerating chamber door to store ice therein, wherein the cold air flow passage extends forward along the shelf so that cold air is discharged to the container. According to the refrigerator of the present invention, even though an ice bank for storing ice is provided in a refrigerating chamber door, it is possible to prevent a phenomenon by which ice is partially melted and stuck again together. Further, since ice is not partially melted and stuck again together, it is possible to prevent a phenomenon by which an overload is applied to an ice crusher provided in the ice bank.

The refrigerator as claimed in claim 1, wherein the cold air duct is provided at any one of a top surface, a bottom surface, or a side surface of the shelf. 4. The refrigerator as claimed in claim 1, wherein a discharging end that includes the one or more openings of the cold air duct is inclined at a predetermined angle so as to discharge cold air. 5. The refrigerator as claimed in claim 1, wherein the container is disposed under the ice maker. 6. The refrigerator as claimed in claim 1, wherein the cold air duct and shelf are located between the ice maker and the container. 7. The refrigerator as claimed in claim 1, wherein the first width extends from a first side edge of the shelf to a second side edge of the shelf. 8. The refrigerator as claimed in claim 7, wherein the first width is substantially equal to a width of the front side of the shelf. 9. The refrigerator as claimed in claim 1, wherein the front side corresponds to a front edge of the shelf. 10. The refrigerator as claimed in claim 1, wherein cold air from the cold air duct flows through a plurality of openings on or adjacent a front side of the shelf. 11. The refrigerator as claimed in claim 1, wherein the direction which is substantially parallel to the front side of the shelf crosses a direction in which the cold air duct extends on or along the shelf. 12. A refrigerator, comprising: a main body including at least a refrigerating chamber and a freezing chamber disposed under the refrigerating chamber;a first and second refrigerating chamber doors for opening or closing the refrigerating chamber;at least a shelf provided in the refrigerating chamber;an ice maker disposed within the refrigerating chamber so as to be located behind the first refrigerating chamber door;a container mounted on the first refrigerating chamber door so as to be supplied with ice from the ice maker and to be exposed to an interior of the refrigerating chamber;a dispenser disposed in the first refrigerating chamber door so as to dispense the ice received in the container;an evaporator disposed within the freezing chamber to supply cold air; anda cold air flow passage for supplying the cold air from the freezing chamber to the container in order to maintain the ice in the container in a frozen state, wherein:the cold air flow passage extends along the shelf and includes a terminal end arranged along or adjacent a front edge of the shelf,the terminal end includes one or more openings for discharging cold air from the cold air flow passage to the container, andthe one or more openings extend along or adjacent the front edge of the shelf for a first width greater than a second width of the container. 13. The refrigerator as claimed in claim 12, wherein the cold air flow passage is a cold air duct extending along a bottom surface or a side surface of the shelf. 14. The refrigerator as claimed in claim 12, wherein the cold air flow passage supplies cold air to the container and the refrigerating chamber. 15. The refrigerator as claimed in claim 12, wherein the one or more openings are coupled to the cold air flow passage and are positioned at a level which is substantially equal to or higher than a level that corresponds to an opening of the container. 16. The refrigerator as claimed in claim 12, wherein an ice maker is coupled to a ceiling of the refrigerating chamber. 17. The refrigerator as claimed in claim 16, wherein the container is disposed under the ice maker. 18. The refrigerator as claimed in claim 12, wherein the dispenser includes an opening through which the ice is supplied, the opening located on an outer surface of the first refrigerating chamber door.
